摘要

摘要: 利用MODIS气溶胶产品中550nm气溶胶光学厚度和小颗粒比例两个参数的关系,直接计算得到我国海域人为和沙尘气溶胶光学厚度,并对人为和沙尘气溶胶的分布进行了分析,结果表明:在我国海域,利用550nm气溶胶光学厚度和小颗粒比例的关系直接计算人为和沙尘气溶胶光学厚度是可行的;我国海域的人为和沙尘气溶胶光学厚度有明显的时空变化.人为气溶胶在春夏季最大,而在秋冬季最小;沙尘气溶胶在冬春季最大,而在夏秋季最小.在该海域人为和沙尘气溶胶光学厚度有显著的空间变化,在纬向上,人为气溶胶光学厚度在30°~45°N达到最大值,向南北递减;沙尘气溶胶光学厚度在33°~40°N最大,在其他纬度都很小.在经向上,人为气溶胶光学厚度与离岸距离有关,在沿海120°E处最大,随着经度增加而减小.沙尘作为大颗粒气溶胶,传输距离小,所以它只是在120°~123°E出现最大值,在其他经度处都很小.

Abstract: The method of estimating anthropogenic and dust aerosol components directly from satellite data is given.The method uses the relationship between the fine mode fraction and the aerosol optical thickness in MODIS data to respectively compute anthropogenic and dust aerosoloptical thicknesses in China for the first time.The result shows that the result obtained with the method is good over the China's seas,and the anthropogenic and dustoptical thicknesses have marked season variation and spatial distribution.In different seasons,the anthropog enic aerosol optical thickness is the largest in spring and summer and it is the smallest in fall and winter.Nevert heless,the dust aerosol optical thickness is the largest in winter and spring and it is the least in summer and fall.They show marked variation along the longitude and obvious variation along the latitude.In the long it udinal direction,the anthropogenic aero so loptical thickness appears to be the maximum value between 30° and 45°N and decreases northwards and southwards,which suggests that human influence is the most serious in this region.Meanwhile,the dustaerosol optical thickness appears to be the maximum value between 33° and 40°N and it is too small at other latitudes,which suggests that the region influenced by dustis limited.In the meridional direction,the anthropogenic aeroso loptical thickness has excellent relationship with the distance far from the coast.The anthropog enic aeroso loptical thickness reaches the maximum value round 120°E which is near the coast and it gradually decreases with the longitude increasing,which is caused by anthropog enic influence.On the other hand,as big particles,dustaerosol is difficult to be transported to remote region,so dustaerosol only affects a small meridional area.The dust aerosol optical thickness appears to be the maximum value between 120° and 123°E and it is too small at other long itudes.
